I'd be more concerned about industry-wide blacklisting.
But I also had a different situation where we also decided to hire someone, only to find out that we can't because he's been let go from another company owned by our parent company, and his severance agreement said he can't work for the same group of companies for 12 months. I think he was genuinely unaware that we're part of the same group(if was a huge corporation) and it just never came up in any conversation until HR tried to put together paperwork for him.
In the USA this is mostly theoretical since HR could immediately fire the employee due to at-will employment.
But in Canada, it's a much bigger issue due to labour protections.
e.g. Many managers at American multinationals gave assurances over email to employees about work-from-home arrangements. Then the company does a huge RTO push.
When the employee refuses, HR discovers they can't fire the employee without a hefty buyout.
Best not to give assurances if you're managing a multinational team.
Is that an American thing? I've been a manager for years and never heard of that happening. I didn't even know how much the people I managed were paid.
